Comment (by Vishy Algo):
So, removing the CASCADE in
''django/db/backends/base/schema.py'' :
{{{#!diff
class BaseDatabaseSchemaEditor:
+ sql_delete_table = "DROP TABLE %(table)s CASCADE"
- sql_delete_table = "DROP TABLE %(table)s"
}}}
, would cause the migration to fail with an integrity-related database
error, preventing the migration from completing successfully.
Hence, removing the divergence happening in the ProjectState object.
